| 摘 要： | 给出了一种用二端口矢量网络分析仪(VNA)对多端口器件进行测量的方法。该方法通过多端口器件的一端口测量得到端口负载,运用Gamma-R参数法减小由于其余端口所接负载的非匹配性引入的误差,并通过Matlab软件实现。利用该方法对三端口双工器进行测量,并将最后结果与三端口VNA测得的结果进行比较,比较结果表明幅度误差小于0.5dB,相位误差小于5度。该方法在多端口VNA不可获得的情况下,可以应用到多端口器件的精确测量上。

| Abstract: | A method for multi-port device measurement using a two-port vector network analyzer(VNA) is presented.This method uses one-port measurement of multi-port device to get port terminations and Gamma-R parameters to reduce the error due to imperfect terminations of the remaining ports.It can be easily implemented in Matlab.A three-port duplexer was measured using this method and the results were compared to the data measured using a three-port VNA.The compared results show that the error of the amplitude is les... |
